Thesis (Ph.D.)--Boston University / The most common polagraphic electrode in use at the present time is the dropping mercury electrode (DME). There are, however, certain well-recognized disadvantages attendant on the use of the DME: (1) oxidation analysis is limited to 0.4 v.; (2) there are rather large charging currents associated with the growing drop; (3) the area of the drops, and hence the sensitivity can not be appreciably increased; (4) because of drop growth, a a spiky sort of current is obtained which introduces a reading error into the results obtained, especially at low concentrations. It can be seen that these disadvantages are largely a function either of the electrode shape and size, or of the method of electrode propagation. [TRUNCATED]
